• Instead of using HTML dragging of elements, now we use custom drag code. Tell me if this causes problems.
• For users building from source, v2.5.8 likely fixes a Lichess API access issue.

• Fix a crash when selecting no online API.

These releases are both bugged and shouldn't be used.

• [2.5.5] A more friendly way to set the Lichess API token now, via Display --> Online API --> Set Lichess API token
• [2.5.6] Updated Lichess API endpoints to explorer.lichess.org

As of Tuesday, the Lichess explorer API (which is optionally used by Nibbler) requires an authentication token.

As a temporary solution, Nibbler 2.5.4 can read a token which is stored in Nibbler's config.json (which you can find via the Dev menu) as the property lichess_token.

To get such a token:

• Login to Lichess at https://lichess.org/login
• Then go to https://lichess.org/account/oauth/token/create
• Create a token there. You do not need to tick any of the boxes, just scroll down and click Create.
• Quit Nibbler if you happen to have it running.
• Now edit Nibbler's config.json file and find the line "lichess_token": "",
• Insert your token inside the quotation marks. Do not delete the quotation marks. Do not delete the trailing comma.
• So now it should look like: "lichess_token": "lip_12345", or whatever.

Perhaps I will make a more elegant solution at some point.

• Fix a rare edge case where triple repetition might not be detected if the first position in the sequence had a fake en-passant square (where the en-passant square is set but the capture is not actually legal).

• The space bar will now toggle analysis on and off, except when in Play mode or Analysis Locked mode.

• Translations for various languages. Mostly machine translations.
• Suggestions and fixes welcome... as a pull request is strongly preferred.
• Also ask for other languages if you like.
• See the file src/modules/translations.js

Currently only menu items are translated. I might expand this in the future to translate other in-app text, if I'm in a good mood, if I have time, if you're lucky, if the stars align, if my cat approves, if the groundhog sees his shadow, barring any unforeseen circumstances, after due consideration, God willing.

• Added some backends to be up to date with the various Lc0 builds.

• Add an option for Leela's WDLEvalObjectivity setting.
• Add a visual indicator if the engine is running with contempt - in case you forget.

• Adds some basic settings in the Engines menu to access Leela's contempt feature.
